I walked into a beautiful colonial on Eagle Street West last Tuesday and immediately smelled that musty, sweet odor that makes my stomach drop. The sellers had done a gorgeous renovation job upstairs, but when I followed my nose to the basement, I found black mold creeping up the foundation walls like spilled ink. The dehumidifier was running full blast, which told me they knew about the problem. Guess what the listing photos conveniently left out?

That's the thing about Newmarket's housing market right now. With 198 homes listed and an average price of $1,155,205, buyers are making lightning-fast decisions on properties that average 40-plus years old. Twenty days on market means you're competing with multiple offers, and I've seen too many people skip the inspection just to win the bidding war. Sound familiar?

What I find most concerning is how many of these 1980s and 1990s homes are hiding expensive surprises behind fresh paint and staged furniture. That Eagle Street house I mentioned? The mold remediation estimate came back at $13,750, and that was before we even talked about fixing the foundation crack that was letting moisture in. The buyers almost walked away, but at least they knew what they were getting into.

I've been doing this for 15 years in Ontario, and I inspect three to four homes every single day. My back aches, my knees creak when I crawl through crawl spaces, and I've probably inhaled more basement air than any human should. But I keep going because I've seen what happens when people don't know what they're buying.

Take the Mulock area, for instance. Those split-levels from the 1980s look solid from the street, but I can't tell you how many times I've found original electrical panels that should have been replaced decades ago. Last month on Brookland Avenue, I found a panel so corroded the main breaker was barely hanging on. The replacement cost? $3,200. The potential cost of an electrical fire? You don't want to know.

Buyers always underestimate what deferred maintenance really means. They see a house that's been lived in for 30 years and think, "Well, at least it's been maintained." But here's what they don't consider: when was the last time someone replaced the furnace filter? When did they service the HVAC system? How old is that water heater humming away in the corner?

I inspected a gorgeous place on Bayview Avenue last week. The kitchen renovation probably cost $60,000, and the hardwood floors were immaculate. But the 22-year-old furnace was on its last legs, and the ductwork had more holes than a golf course. The heating bills were probably astronomical, and come April 2026, they'd be looking at $9,400 for a new system plus another $4,800 to fix the ducts.

The risk score for Newmarket sits at 56 out of 100, which means you're dealing with moderate risk factors across the board. Age is the biggest factor here. These aren't century homes with character issues, but they're not new builds either. They're right in that sweet spot where major systems start failing all at once.

I remember a house on Prospect Street where everything looked perfect during the showing. The sellers had clearly put money into curb appeal and staging. But when I got into the basement, the support beam had a crack running along its entire length. The structural engineer's report wasn't cheap, and neither was the $11,300 repair estimate.

In my experience, the neighborhoods east of Yonge Street tend to have better-maintained homes, but they also command higher prices. The older subdivisions around Stonehaven and Eagle Street can be goldmines or money pits, depending on how the previous owners treated them. You really can't tell from the outside.

What breaks my heart is when I meet young families stretching their budget to afford that $1,155,205 average price tag, and then I have to tell them about the $15,000 in immediate repairs they'll need. I've seen couples sitting in their car after an inspection, calculator in hand, trying to figure out if they can make the numbers work.

Here's my honest opinion: if you're buying in Newmarket right now, you need to budget at least $10,000 for unexpected repairs in your first year. I don't care how good the house looks or how well the sellers maintained it. Forty-year-old systems fail. It's not if, it's when.

The foundation issues I see most often relate to poor grading and inadequate drainage. These homes were built when building codes were different, and I regularly find basement moisture problems that have been bandaided rather than properly fixed. That sweet smell I mentioned earlier? It's not always mold, but it's never good news.

Last Thursday, I inspected a split-level on Timothy Street that had been beautifully updated throughout. New kitchen, new bathrooms, fresh paint everywhere. But the roof was 18 years old and showing its age, with three or four shingles that had already blown off. The sellers hadn't mentioned it, probably didn't even know. But come the next windstorm, that family could be looking at water damage on top of the $8,900 roof replacement.

I've never seen a market move this fast where buyers have this little time to make informed decisions. But that doesn't mean you should go in blind. The most expensive mistake you can make is assuming everything's fine because it looks fine.

Don't let the speed of Newmarket's market pressure you into skipping the inspection. I've been crawling through these houses for 15 years because I've seen too many people get burned. Call me before you sign anything, and let's make sure you know exactly what you're buying.
